Title: Spectrophotometer with light source in the form of a light emitting diode array
Inventor: WEBSTER DONALD R
IPC: G01J3/10
Filed: 1995-10-06
Abstract: In a spectrophotometer, a light source is provid-ed in the form of a multiplicity of light emitting diodes which transmit light through an entrance slit to irradiate an oscillating grating. The light is dispersed by the grating toward an exit slit which transmits a narrow bandwidth of light to irradiate a sample. As the grating oscillates, the wavelength transmitted through the exit slit is scanned through a selected spectrum. The diodes in the array each emit light in a different wavelength band so that the diodes as a group emit light throughout the selected spectrum. As the grating oscillates, the diodes are energized and extinguished in sequence so that no more than two diodes will be energized at any given instant of time and the energized diode will be emitting light at the wavelength dispersed by the grating to the exit slit.

Filed: 1995-10-26
Abstract: A plasma display having a quartet type pixel structure provides a high grade and excellent picture quality picture and maintains good white balance and excellent intensity levels. The plasma display comprises a reference circuit .SLZERO. for outputting a control signal based on the least significant bit of a digitized green video signal and a timing signal and an arithmetic circuit 8 for performing an arithmetic operation on the output of the reference circuit. As a result of this arrangement, the least significant bit information, that was lost by halving the green signal value to maintain the white balance is incorporated in the halved green signal based on a timing signal, thereby realizing 256 intensity levels without degrading the halftone in the video picture.

Patent CA-2166343-A1 (CA)
Inventor: HARTLEY LEE F
IPC: H04L12/413
Filed: 1995-12-29
Abstract: A Carrier Sense Multiple Access with Automatic Abort collision avoidance (CSMA/AA) controller for application in a wireless local area network (LAN).  The CSMA/AA controller reduces the number of invalid states arising from collision conditions on the communication channel.   The controller features hardware logic control for time critical functions. The  hardware  logic  circuit  detects  events  and  fault conditions under the CSMA reservation protocol which may otherwise be missed by the Medium Access Control software layer and aborts the transmit procedure.  The off-loading of time critical functions also improves the performance of the system and reduces the variability arising from overhead execution times associated with the system CPU.

Inventor: YANIGER STUART I
IPC: G01C9/14
Filed: 1994-08-04
Abstract: A two-axis tilt sensor, or inclinometer (10), uses a spherical reference element (18) floating in an inert fluid (20) and including a magnet (42) to produce an asymetrical weight distribution. The asymetrical weight distribution maintains the spherical reference element at a constant orientation with respect to gravity, while the position of the magnet on the spherical reference element with respect to a housing (12) is detected by opposing pairs of Hall effect sensors (22) mounted on the housing. The outputs from opposing pairs of sensors are processed by differential amplifier circuits (80) to determine signals corresponding to the tilt of the inclinometer about the axes.

Title: Roller shutter slat
Inventor: ERBER ANDREAS
IPC: E06B9/386
Filed: 1994-12-29
Abstract: A roller shutter slat has hollow sectional slats (1) with a central part (1c), two edge parts (1a) and transverse grooves (1b) arranged therebetween for receiving bearing or adjusting links (3,4). The edge parts (1a) and the central parts (1c) are spaced apart and interconnected by linking elements (5, 6, 40, 41) inserted into hollow chambers (26) of the hollow sectional slat (1). The cross-section of the linking elements (5, 6, 40, 41) is narrower than the cross-section of the hollow chambers (26) and the linking elements (5, 6, 40, 41) are linked to the hollow sectional slats (1) by tongue-and-groove joints (9, 10; 42, 43). Easy-to-produce grooves (1b) are thus created without weakening the roller shutter slat (1) in the area of the grooves (1b).
